Question

What are the differences between autotrophic nutrition and heterotrophic nutrition?​

Answer 1

Answer:

"Autotrophs are organisms that prepare their own food through the process of photosynthesis, whereas heterotrophs are organisms that cannot prepare their own food and depend upon autotrophs for nutrition".

Answer 2

Autotrophs:

1. Usually members of the plant kingdom and certain unicellular organisms like cyanobacteria.
2. Autotrophs are producers which prepare their own food.
3. These can be classified as photoautotrophs and chemoautotrophs.
4. The chloroplast helps in preparing food.
5. They obtain energy from inorganic sources by converting light energy into chemical energy.
6. Autotrophs can store light energy and chemical energy.
7. They are placed at the primary level in the food chain.
8. Green plants, algae and a few photosynthetic bacteria are examples of autotrophs.

Heterotrophs:

1. All members of the animal kingdom.
2. Heterotrophs are the consumers who depend on other sources for their food.
3. These can be classified as photoheterotrophs and chemoheterotrophs.
4. They do not contain chloroplast, so cannot prepare food.
5. They obtain energy directly or indirectly from other organisms.
6. Heterotrophs cannot store energy.
7. These are placed in the secondary or tertiary level in the food chain.
8. Cows, buffaloes, tigers, horses, humans are examples of heterotrophs.
